. Значение проекта для команды. Этот проект имеет для нас большое значение. В ходе его создания мы работали с книгами, были в библиотеках, искали нужный нам материал. Так же мы узнали многое о русских историках и думаем, что эти знания пригодятся нам в будущем. Но проект "Российские историки XIX века" полезен не только в историческом плане, он еще помог узнать структуру HTML - документа, что в наше время немаловажно. Каждому третьему трудящемуся в годы технического прогресса компьютер просто необходим.
